A barbiturate-functionalized supramolecular monomer bearing an ester-linked biphenyl and azobenzene π-conjugated core affords wavy supramolecular polymers. The periodic inversion of curvature is due to the conformational rigidity of the monomer and repulsive interactions between rosettes. Photoisomerization of the azobenzene moiety increases the fragility of the main chain without deteriorating its periodic structure.
一种带有酯键联联苯和偶氮苯π共轭核的巴比妥酸功能化超分子单体提供了波浪形超分子聚合物。曲率的周期性反转归因于单体的构象刚性和蔷薇花样之间的排斥相互作用。偶氮苯部分的光异构化增加了主链的脆性，而不会破坏其周期性结构。
